The symptoms may last for several weeks and some neurological effects could be permanent.

The health department advises people follow these "Drain and Cover" tips:

Drain standing water to stop mosquitoes from multiplying:

Drain water from garbage cans, house gutters, buckets, pool covers, coolers, toys, flower pots or any other containers where sprinkler or rain water has collected.

Discard old tires, drums, bottles, cans, pots and pans, broken appliances and other items that aren't being used.

Empty and clean birdbaths and pets' water bowls at least once or twice a week. Protect boats and vehicles from rain with tarps that don't accumulate water.

Maintain swimming pools, keeping them in good condition, and appropriately chlorinated. Empty plastic swimming pools when not in use.

Cover skin with clothing or repellent:

Clothing: Wear shoes, socks and long pants and long-sleeves. This type of protection may be necessary for people who must work in areas where mosquitoes are present.

Repellent: Apply mosquito repellent to bare skin and clothing. Always use repellents according to the label. Repellents with DEET, picaridin, oil of lemon eucalyptus, and IR3535 are effective. Use mosquito netting to protect children younger than 2 months old.

Cover doors and windows with screens to keep mosquitoes out of your house:

Repair broken screening on windows, doors, porches and patios.

Tips on Repellent Use

Always read label directions carefully for the approved usage before you apply a repellent. Some repellents are not suitable for children.

Products with concentrations of up to 30 percent DEET are generally recommended. Other EPA-approved repellents contain Picaridin, oil of lemon eucalyptus, or IR3535. These products are generally available at local pharmacies. Look for active ingredients to be listed on the product label.

Apply insect repellent to exposed skin, or onto clothing, but not under clothing.

In protecting children, read label instructions to be sure the repellent is age-appropriate. According to the CDC, mosquito repellents containing oil of lemon eucalyptus should not be used on children under the age of 3 years. DEET is not recommended on children younger than 2 months old.

Avoid applying repellents to the hands of children. Adults should apply repellent first to their own hands and then transfer it to the child's skin and clothing.
